Long-term materials testing on the ISS

Through our partnership with Applied Minds we were invited to include one of our materials on a NASA material experiment called MISSE on the International Space Station. We included a sample of commercially pure titanium, that was black oxide coated, and laser etched (pictured below). This is the same material/process that we made the front side of the Rosetta Disk out of. Now we get to find out how well the disk would hold up if exposed to open space for several years...

This experiment is a continuation of sorts of the material research started back in 01984 with the Long Duration Exposure Facility that Kevin Kelly posted about earlier.
